LISTER- CULTIVATOR.

To all whom it may cancer a: I

Be it known that I, VESLEY A. PAUL, a

citizen of the United States, residing at Moline, in the county of Rock'lsland and State of Illinois, have invented'certain new and useful Improvements in Lister-Cultivators, of-which the following'is a specifi cation, reference being had therein to the acadapted to cultivate two rows simultaneously, and having gangs of cultivating de-.

vices flexibly and adjustably connected -to the opposite ends of a spreader-bar.

. The objects of my invention are to construct the cultivator so that the gangs may have sufiicient freedom of movement laterally to better conform to any deviation of the furrows from a straight course; to improve the adjustability of the gangs, and to simplify the construction and operation'.

Referring to the accompanying drawings in which similar numerals of reference indicate indentical partsFigure 1 is a plan view of a lister-cultivator containing my improvements. of one of the gangs. Fig. 3 is a side elevae-tion. Fig. 4 is a detail in part section.

Figs. 5, 6, 7,3, and 9 are views of various parts of the gangs as will be hereinafter fully described.

At each end of the spreader-bar 1 is flexibly connected a gang of cultivating devices, and as they are similar in construction and operation, a description of one gang will suffice for both, reference numerals used being identical in both gangs.

A frame-bar 3 is supported on ground; wheels 4 and 5 journaled on standards 6 and 7 clamped to the frame-bar and capable of adjustment to or from each 0 her to vary the space between the wheels to accommo-.

date the width of the furrow. The tongue is composed preferably of two parts, the rear part 9 being preferably of channel steel and rigidly secured to the forward part 10 which may be either of wood or metal,

Bolted to the rear of the part 9 is a transverse bar 11, its ends bent rearwardly to register with forward ends of brackets 12' and-13 and pivotally secured thereto, the

. brackets 12 and 13 being clamped to the frame-bar 3. -Cultiv'ating devlces consisting of beams carrying disks or shovels and projecting rearwardly, are secured to the frame-bar 3 in the following manner; Projecting rearwardly and pivoted at their forwhich are journaled cultivating disks 17,

adjustable for inthrow or .outthr'ow by changing them from one side tothe otherof the downwardly bent portions of the beams 14 and 15. The brackets 12'and 13 extend rearwardly of the pivotal points of the beams 14 and 15 thereon, and have horizontally disposed arcuate slots 18, receiving bolts 19 and 20 in the beams 14 and 15 the ends of the bolts are threaded for nuts 21. and 22, sothat the beams 14 and 15 can be securelyheld in any position of lateral adjustment'to which thev may be swung on thelr pivotal connection to the brackets 12 and 13.

Extending through the frame-bar'S, rockable therein, and of greater length to pro-- ject beyond the ends thereof, is a rock1ngbar 23, on which are secured brackets 24 adjacent the ends of frame-bar 3; rearwardly extending beams 25 and 26 are pivoted on brackets 24 rearwardly of the rock- '85 ing-bar 23 and are secured in any position of lateral adjustment in a similar manner as beams 14 and 15; on the rear, end of beams 25 and 26 are adjustable standards 27 and 28 fitted with shovel blades. Additional cultivating devices may be mounted on the extreme ends of the rocking-bar 23 as shown.

The bracket 24, on the inner end of the rocking-bar 23, has an upwardly projecting arm 29 to which is secureda lever 30 engaging, by latch thereon, ,with a segment 31 on the framebar 3, so that the bar 23 can be rocked to raise or lower the cultivating, devices thereonirrespective of the-adjust 10'0 ment ofthe frame-bar 3 and-its cultii 'ating devices. A coiled'spring 31 connectedto the segment 31 and to"a "member-26'-'=on the beam 2,-'and adds materially to thefacility, l of raising or lowering. the cultivating ,de- 1-135 vices by rocldng thebeam'. 3. 5,.a-Th "lever 310- extreme nicety of adjustment of the cultivating devices on the rocking-bar 23.

Flexible connection of each of the gangs with the spreader-bar 1, cons sts of a for- Wardly extending link 32'hav1ng a vertical, sleeve or socket 33 at its forward end,

idly mounted on the tongue; at the rear end of the link 32 is a similar vertical socket 35 engaging with a pin 36 rigidly connected .to the lower portion 37 of a clamp 38 on the 's reader-bar 1. Beneath each link, preferably integral therewith and rearward of the socket 3 3,is a web 39 whichextendsrearward a sufficient distance to-engage' with stops 40 and 41 on the rear of the tongue, to limit the lateral swing of the l nks 32 and the spreaderbar 1. Midway of the spreader-bar l-a seat 42is mounted on a support 43 firmly-bolted to the spreader bar," andextending forwardly and down wardly, "and having a'foot-rest 44 secured to the forward end. I r

Pivotally mounted on each tongue 1s a forked lever, 45,, straddling the tongueand with the tongues, and when the tongues are lncl'ned upwardl ,as during the operation extending below it to connect with'draftrods 46 and 47 which are connected to the standards 6 and 7. The upper :end of the forked lever 45 isjoinedby'fa rod 48 to a lever 49 pivotally mounted on the tongue and fitted with a latch to engage with a segment 50 also mounted on the tongue. A whiffietree 51, to which horses are to be hitched, is connected to. a link 52 on the lower ends *of the forked lever 45. By thev construction just described it is apparent .that, after the cultivating devices have been lowered to contact with the ground and the latch on the lever 49 disengaged-fromi'the segment 50, the draft of the team will be employed to .force the cultivatingdevices into the soil.

The links 32 supportingspreader-ban1 upon which the seat is mounted, have their horizontal portions substantially parallel of the r chine, t 1e links have a rearwardly downward inclinat on; ordinarily this would result destroying the balance of the machine by the weight of the driver; but as the devicesattached to the frame-bar. links are'prvoted forwardly -on the'tongues,

- and the latter are pivotally connected to the" wheels 4,and 5, the weight of the driver tends to ofisetithe weight ofthe cultivating-v ilei'ices wfhelilrthe latter are raisedand the I )a ance o t ev machine is more easilgmain the rockin tained. 'By the rearward and doviinwardl gibdim 'zm'd'plyoted rearward of the inclination of-links 32 their lateral movement- 1s';I nore quickly responsiveto laterat' anovementof the gangs when following inequalities in the rows being cultivated, and

the, central position of the drivers seat :on'

the spreader-bar, in relation to the gangs, is more easily maintained.
